Hi, I went to a person to do some cosmetic vinyl wrapping on my car last week. The person is a small business with an ABN who sent through an invoice for the work before I got there. The person could not get it to work and in turn could not get the job done. The person said he will order more vinyl and that we will do it next week. I did not state that I would return and that I would get back to him later in the week with a date. I never contacted him because I did not want to return as he showed he was unskilled. Yesterday (Tuesday) he texts me saying that my replacement vinyl is here and that he will see me tomorrow, I do not respond to the message. Then last night he sends me through an invoice for the vinyl and on the invoice it mentions that I did not show up and I did not give him notice of cancellation. Do I have to pay this under Australian Consumer Law? There was no agreed upon time, I did not receive a service as my car is the same as when I gave it to him and by not contacting him I thought it was clear I did not want to return.
